MIRNEWS.355 19 APRIL 1997
MIR-routine:
Immediately after the opening of the hatches to Progress-M34 the crew began
to unload the most important stuff for dir ect use. They used a part of the
new arrived pure oxygen supply and new lithium perchlorate 'disks' for
oxygen product ion. Radiotraffic revealed that the cosmonauts without delay
had started the repair otf the Elektronsystem in Module-D (Kvant-2). On
11.04 this Elektron was activitated, but after a few minutes during which
oxygen was produced it switc hed itself off. On the days to follow the crew
regularly worked on this system and to undo the last failure they even used a
part of the unserviceable Elektron in Module-E (Kvant-1). The urgent work
on the Elektron caused a considerabl e work overload of the crew. These days
the astronaut Linenger is often deployed to assist in this repairwork for
which
he has to refrain from a part of his American experiments. A few times the
work on the Elektron had to be suspended fo r the execution of repairwork
with a higher priority. This had to do with a lot of leakages in the
heating- and coolin g circuits in the Base Block and Kvant-1. The leaks in
the cooling loops in Kvant-1 caused the outflaw of cooling liqu id (ethylene
glycol) and the decrease of the pressure within that circuit. A sufficient
cooling is also needed for th e functioning of the carbondioxyde (CO2)
absorber Vozdukh. For the neutralization of CO2 in MIR's atmosphere there is
another alternative. Progress-M34 delivered for that purpose canisters
lithium hydroxyde. Meanwhile the Elektron in Module-D and the Vozdukh CO2
scrubber are functioning. The problems with the lifesupportsystems on board
caused a high
humidity and consequently a lot of condensation. Twice a day Tsibliyev can
be heard reporting pulse rates, blood pre ssures, skin temperatures and blood
oxygen saturation of all crew members.
Orbitcorrection:
Using the engines of the Pr-M34 the orbit of the MIR-station had been
corrected on 15.04.19997 at 12.46.01UTC. Apogee and Perigee changed from
397.16/381.63KM to 402.54/389.51 KM.
Solar orbit:
Within a few days MIR will enter a so called solar orbit. During this period
MIR will continuously remain in sunlight.
Then it will be more difficult to control the on board temperatures.
Tsibliyev said that physically the crew is able to sustain this
inconvenience, but that he has some concerns about the equipment of the
complex.
1st Spacewalk (EVA) MIR Main Expedition 23/ NASA 4:
This EVA is (or possibly meanwhile: was) on schedule for 29.04.1997. The
EVA will be executed if the repairworks can
be accomplished before a determined deadline.
